Fresh off the boat from Europe ECS Tuning has N52 Euro Airboxes in stock!

Add European performance and convenience to your US spec E9X

If you have ever tried to replace your stock air filter on your N52, you'll be all too familiar with the lengthy process of removing the airbox to simply check on your air filter. BMW offered a solution to this in the European market, with this top-loading style airbox. Simply remove the top panel and you have easy access to your air filter.

Further advantages over conventional airboxes include a less restrictive system: American market airboxes use a panel filter in conjunction with a secondary filter/muffler that greatly impedes airflow. Utilizes a cylindrical type air filter instead of a flat panel filter.

The Euro Airboxes are currently out of stock. More are on the way and slated for delivery on the 27th of February.

The Euro air box has OEM fitment, and provides better air flow than the stock us spec air box. The Euro Air Box design allows cool air to be passed into the air filter without heavy restrictions. The Air Box design also helps keep heat (the killer of power) away from the intake where many aftermarket options do not.

PM me your best price shipped to 28277.. also what are the gains vs stock US spec OEM intake, I understand you don't have numerical calculations but if you could make an educated guess, also an noticeable increased throttle responsiveness vs stock US intake... Thanks in advance

The advantage over the stock air box is a less restrictive system: American market airboxes use a panel filter in conjunction with a secondary filter/muffler that greatly impedes airflow. The Euro Box utilizes a cylindrical type air filter instead of a flat panel filter. As for other improvements most users report a noticeable increased throttle response.
